Replace Your Non-Functioning ST7000 Head Unit with Nauti-Control ST Wireless

Many Raymarine autopilot systems built around the ST6000, ST7000, and similar SeaTalk-based control heads are still powering boats around the world today. While the core autopilot course computer and drive units often remain in excellent working condition, the head units themselves are prone to age-related failures and are no longer supported by the manufacturer.

If your ST7000 or ST6000 display has failed but the rest of your autopilot system is still operational, you don’t need to scrap the entire system. The Nauti-Control ST Wireless Controller provides a modern, affordable replacement that integrates directly with your existing SeaTalk network — restoring full control without the need for expensive proprietary parts.

Why ST Head Units Fail

Over time, the original ST series control heads (ST6000, ST7000, ST7001 etc.) suffer from:

LCD screen failure or missing segments
Button membrane wear and non-responsive keys
Water ingress or corrosion on internal connectors
Component ageing from decades of service

Replacement parts are increasingly scarce, and even used units are often unreliable or overpriced. This is where Nauti-Control ST steps in as a smart, future-proof solution.

Nauti-Control ST: A Modern Replacement for Legacy SeaTalk Head Units

The Nauti-Control ST Wireless connects directly to your existing SeaTalk network, providing full autopilot control without requiring any modification to your current system. It effectively replaces the functionality of the old head unit while adding new wireless features.

Key features include:

Direct SeaTalk connection – plug-and-play with classic Raymarine autopilot systems
Wireless control via 433 MHz remote or smartphone
Wi-Fi and Bluetooth connectivity for setup and control
Compact, waterproof design ideal for modern installations
Mobile app support for Android and Wear OS

The result: full control of your autopilot system without the need for obsolete parts or costly refits.

Compatibility

The Nauti-Control ST has been successfully tested with:

Raymarine ST1000 / ST2000 tiller pilots
Course computers such as Type 100, 300, 400, 150 and 4000
Any system using the SeaTalk 1 bus for communication

Because it uses the same SeaTalk signalling, it seamlessly integrates into your existing wiring. There’s no need to remove the course computer or drive unit — simply replace the broken head unit and you’re back on course.

Easy Installation and Setup

Installation is straightforward:

Disconnect the old head unit from the SeaTalk bus.
Connect the Nauti-Control ST to the same SeaTalk line using the provided connector.
Power on your system – the controller will automatically detect and communicate with your autopilot computer.
Configure wireless features and button mapping through the built-in web interface or mobile app.
